Detailed Description

the logical layout of a byte array table for a view

Given the values for

number of bytes per line,
a possible offset of the first line displayed,
a possible offset of the displayed bytearray, and
length of the byte array as well as
offset in the byte array
the number of lines per page jump the following values are calculated:
starting line of display,
starting position in this line,
final line of display,
final position in this line, and
the total number of lines (is final line +1 or 0)

This layout sees the buffer as a continuous stream of byte, thus uses each line after the start from the begin to the end.

If the buffer is empty the end coord will be set one pos left to the start coord to easen the cursor handling.
